Hi,
Do you mean actual level of a digital signal or a process level like amount of water in a tank?

This depends on the type of measurement:
Liquid level
Pressure
Temperature
?
Are the measurements in discreet steps like upper limit / lower limit
or
Defined range like 0 - 100Kpa or 0 -10cm Hg with infinite number of steps (analog) or 2n steps (digital) ?

There are liquid pressure sensors available that give industry standard 4-20ma output. Probably the best long term reliability, they would require calibrating to compensate for the shape of the tank, probably a lookup table if irregular size.

Hi dears,
Which one do you want to design??
Ultrasonic
Liquid level sensor…?
Flow
Temperature
Pressure…
Ultrasonic is of low cost with high performance you would like to. The liquid sensor has a compact and solid state design. You will need the LR series for measurement purposes and all the stainless steel and pushbutton setup.
Thanks
